The body of a dump truck is raised to empty a load of dirt. how high is the 10 inch body from the frame when it is tipped upward at 45 degrees? round to the nearest inch.

7 ft

Step-by-step explanation:

First of all, "10 inch" would be "10 feet".

Now,

the height of the body from the frame at 45% angle would create a 45-45-90 degree triangle.

From the triangle, the body height (h) divided by  would give us the approximate height of the body from the frame.

So,

So, the 10 feet body would be around 7.07 feet from the frame. Rounded to nearest inch, it would be 7 feet.

step-by-step explanation:

introduction, methodology, results, discussion

step-by-step explanation:

an observational study is one which consists of actual observation to record data and then analyse the data.

the main four factors are:

i) introduction:   this should be analysed to check whether the purpose of the study is correctly established and the data recorded are appropriate for the study

methodology:   the method of collecting the data, such as whether randomly selected, and whether sample size matches with the population to be studied, whether questions asked are easy to answer by common men, etc.

results: then results such as summary of data with comments should be studied thoroughly

discussion:   the last is the discussion, this can be either by management people or persons who are all interested , etc.
